   Şantiye ERP — arayüz stilleri

   Tasarım kararları:
   - Harici font/CDN kullanılmaz. Şantiye bilgisayarları ve zayıf internet
     bağlantısı düşünülerek her şey yerel ve sistem fontlarıyla çalışır.
   - Yoğun veri tabloları esas alınmıştır: satır yüksekliği düşük,
     sayılar tablo rakamlarıyla (tabular-nums) hizalı.
   - Palet şantiye ekipmanından alınmıştır: koyu mürekkep, beton grisi,
     makine sarısı. Renk yalnızca durum bildirir, süs değildir.
